We thought we would probably be able to find someone on here to answer our questions better than anyone else. On the exhaust manifold we were trying to find what the tightening sequence is and also how many ft lbs. of torque to tighten too? Thanks!

The bolts are a special bolt from AGCO only. Do NOT use the lockwashers they use. Get a hardened Grade 8 flatwasher.  45 ft lbs with lubed threads.

Doc, does that apply to all 301's or just the 8010?

ALL 301's have a special exhaust manifold bolt that has "self-locking" threads. The hard flat washer is my deal because I've seen too many broken lockwashers over the years and then that blows an exhaust gasket when the lockwasher has fallen out of place leaving the bolt loose.
